Before you can start to treat your allergies, you need to find out what you're allergic to through allergy testing. There are many different allergy tests, and your doctor may recommend the best one for you, depending on your circumstances. Here's at some of the most common types of allergy.

Skin Prick Test

The skin prick test is a quick and easy way to determine if you're allergic to something. A small amount of the suspected allergen is placed on your skin, and then a needle is used to prick the surface.

If you're allergic to the substance, you'll usually develop a red, itchy bump within a few minutes. The skin prick test is accurate as it can show whether you have an immediate allergic reaction.

There's a small risk of developing a serious reaction during the test, so it's important to be closely monitored by a medical professional. If you have a history of severe allergies, you may want to consider getting an allergy blood test instead.

Blood Test

An overreaction of the immune system causes allergies to a foreign substance, such as pollen or pet dander. When a person with allergies comes into contact with an allergen, their body releases antibodies called Immunoglobulin E (IgE). These antibodies cause mast cells in the body to release histamine and other chemicals. The chemicals, in turn, cause symptoms such as itching, swelling, and difficulty breathing.

A blood test for allergies measures the level of IgE in the blood. The test can identify the specific allergens that trigger a person's symptoms. It is often used to confirm the results of a skin prick test.

Blood tests for allergies are generally safe and well-tolerated. But if you have concerns about having a blood test, be sure to discuss them with your healthcare provider.

Patch Test

A patch test is used to determine if a person is allergic to a certain substance. It involves applying a small amount of the substance to a patch of skin and then observing the area for signs of irritation.

Allergists or other medical professionals typically perform patch tests. The results of a patch test can be used to help diagnose allergies and select appropriate treatments.

Patch tests can identify allergies to various substances, including cosmetics, fragrances, metals, and chemicals. They are usually done over the course of a few days. During this time, the patient will need to return to the office so that the allergist can check for signs of irritation. The results of a patch test are typically available within a few days.

In most cases, the allergist will be able to tell if you're allergic to a substance based on the appearance of your skin. However, in some cases, further testing may be necessary to confirm the results.
